Abstract

Bei einer Vorrichtung zum Erkennen einer Unterspannungsversorgung einer Mehrzahl von an einer gemeinsamen Spannungsquelle liegenden Hallsensoren H1, H2, H3, die derart angeordnet sind, dass sie an ihrem Ausgang bei Bewegung eines Bauteils alternierend ein Hochpegelsignal und ein Niederpegelsignal abgeben, wobei die Höhe des Hochpegelsignals von der Höhe der Versorgungsspannung abhängt und die Anordnung und Anzahl der Hallsensoren derart ist, dass ständig wenigstens ein Hallsensor ein Hochpegelsignal abgibt, liegen die Ausgänge der Hallsensoren parallel zueinander an einer Spannungsmesseinrichtung 50, an deren Eingang eine Spannung liegt, die im wesentlichen der höchsten Spannung der Ausgangssignale entspricht, wobei die Spannungsmesseinrichtung ein Fehlersignal erzeugt, wenn ihre Eingangsspannung einen vorbestimmten Schwellwert unterschreitet.
